TOBACCO-PIPE.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed February 26, 1913. Serial No. 750,887.

to be a full, clear, and exact description of I the invention, such aswill enable others skilled in the art to which it appertams to make anduse the same.

This invention relates to tobacco-pipes, and

has for its object the provision of a simple and eflicient device forpreventing the clogging up of the smoke channel by the entrance of bitsof tobacco into it, or by the closing of the orifice at the bottom ofthe bowl leading into the stem, and at the same time to provide anentrance way for air across the entire bottom of the bowl.

Other objects are to provide for easily cleaning the bowl and to avoidrecesses or pockets in which the nauseating liquids so annoying to asmoker may collect.

The invention will first be hereinafter more particularly described,with reference to the accompanying drawings, which form a part of thisspecification, and then pointed out in the claims at the end of thedescription. In said drawings I have shown my improvement applied to apipe with a straight stem but it is applicable to any kind of pipe,straight, crooked, bull-dog, Hungarian or what-not.

Figure 1 of said drawings represents a longitudinal sectional view,taken through the center of a pipe, showing embodied therein thepreferred form of my invention; Fig. 2 is a top plan view of the pipeshown in Fig. 1; Fig. 8 is a longitudinal sectional view taken throughthe center of a pipe showing embodied therein a modification of myinvention, and Fig. 4 is a vertical sectional View taken on the line4.-1 of Fig. 3.

Referring to said drawings, in which the same letters of reference areused to denote corresponding parts in different views, the letter A maydenote the pipe bowl, B the stem and C the mouth-piece detachablysecured to the stem B.

which is placed a coiled spring D, of sufli'.

As shown in Fig. 1, the smoke channel I).

retain .it in place when compressed and pushed down into the bowl untilthe ends thereof fit into the recesses a c at the opposite ends of theenlarged portion of the smoke channel.

As shown in Fig. 2, rect-ly under the bowl and in the stem only, andserves to prevent the clogging of the smoke channel or the closing ofthe orifice cient length to exert a pressure that will 1 the spring Dlies dii at the bottom of the bowl leading into the stem, by preventingthe entrance of bits of tobacco therein, and at the same time acts as astrainer and greatly facilitates the passage of air from the bowl intothe stem. This simple contrivance also distributes the entrance way forair and smoke across the entire bot-tom of the bowl. The open core ofthe spring being in line and continuous with the bore of the stem andmouth-piece also adapts the pipe to be easily cleaned by inserting apointed instrument or ordinary cleaner through the stem and into thebott m of the bowl.

In the modification shown in Fig. 3, the smoke channel extends to therear of the bowl constituting in effect a continuation of the recess inthe bottom of the bowl in alinement with said channel and the spring Dis slightly smaller in diameter than the smoke channel, andsomewhatlonger,being adapted to fit snugly therein, and is inserted byremoving the mouth piece, which may be either of the style known as pushstem or whichmay be fastened to the stem by means of athreaded stud cscrewed into an interiorly screwthreaded socket in the stem. The springis inserted through the smoke channel until oneend thereof rests in therecess a in the rear wall of the bowl, and the mouth-piece is thenpushed or screwed on so as to compress the spring which is held in placeand tensioned by the pushing or screwing into place of the mouth-piecein the stem.

The advantages of the described construction are obvious. A neat anddesirable pipe is produced in which clogging of the stem is obviated,and when cleaning becomes neces sary, any ordinary pipecleaner may beinserted through the stem, or if a cleaner is not handy the point of apen-knife may be inserted through the bowl, and the passage of air fromthe bowl into the stem is greatly facilitated, because of the good cleandraft provided by the large surface of the spring exposed in the bottomof the bowl, and all hollows or crevices in which the noxious liquidsand gases so common to most pipes can collect are eliminated.

It will be understood of course that other kinds of springs might beused inst-ad of the spiral form shown, and that other changes may bemade in the construction and arrangement of parts without departing fromthe-spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1,. In combination with the bowl of a tobacco pipe, a coiled sprinseated. in the bottom of said bowl and having the opening through thecoil arranged in alinement with the smoke channel through the pipe stem.

2. In a tobacco-pipe, the combination of a bowl having in its bottom arecess extending across the bowl in alinement with the smoke channel,and a spiral spring fitting in said recess with one end seated againstthe rear of the bowl and its other end extending into said smokechannel, its ends abutting oppositely disposed shoulders at oppositeends of said recess.

3. In a tobacco-pipe, the combination with a bowl, of a, stem providedwith a smoke channel, a recess in the bottom of the bowl in alinementwith said channel, and compressible spring fitted in said recess andextending entirely across the bottom of the bowl.

4.. In a tobacco-pipe, the combination with a bowl, of a stem and amouth-piece adapted to be attached to said stem, a compressible springarranged within the bowl in alinement with the smoke channel in saidstem and extending entirely across said how], together with means forholding said spring in place.

5. The combination with a tobacco pipe having a bowl, a stem, and adetachable mouth-piece, of a compressible spring fitting in said stemand extending across the bot tom of the bowl; said spring having an opencenter forming a continuation of the smoke-channel in the mouth-piece,and means for confining said spring in position within the stem andbowl.

6. In a tobacco-pipe, the combination with a bowl, of a coiled springfitting across the bottom of said bowl and held in place solely by itsexpansive force; the open center of the spring being in alinement withthe smoke channel in the pipe stem.

In testimonv whereof I affix m 1 si nature I in the presence of twowitnesses.
